550cc Injectors and Fuel Rail? Good PRICE?

[Silvia_Freak]

My friend is selling me his 550cc Rc Injectors and a FUel Rail..For 120$ Is that a steal..It still works and everything he is just upgrading...Im am also buying a new FPR Rising rate....Are the ebay ones alright? Or does anyone have one that is good and tested already...Will I be wasting more gas with 550cc injectors..SHouldnt the fpr regulate gas for driving, if im correct..Please correct if im wrong..Thanks in advance.

Sounds like a good deal on the injectors/rail. You'll need a retuned ECU or a piggyback (SAFC, Emanage) to control the injectors. The FPR will only control how much fuel pressure the injector will see and the ECU/piggyback controls how long it stays open.

I dont know much about the FPR, but maybe the stock one can do (if youre gonna run stock fuel pressure) and you can spend that money on a SAFC or something similar...

Go emanage, SAFC is for chumps who can't figure out timing control . You're going to need a bigger pump, and if you go walbro I would definately suggest a FPR, since mine was running 55psi on the stock FPR.
